HTS-PM04X Series High-temperature Pressure Transmitter
    Publish time 2026-06-25 16:39    

The HTS-PM04X series high-temperature pressure transmitter utilizes an oil-filled diffused silicon sensor core—or a high-temperature sapphire sensor—as the sensing element. Featuring an integrated design that incorporates cooling fins on the process connection for heat dissipation, the unit employs specialized digital  circuitry to process signals through amplification, linearity and temperature compensation, as well as anti-interference and surge protection, ultimately outputting an industry-standard signal suitable for high-temperature environments. An additional external radiator can be attached to enable pressure measurement at even higher temperatures.
